Gigalight Starts Batch Production of 40G QSFP GEN2 Optical Transceiver

Gigalight announced last Friday it’s gone into the batch production of their newly released 40G QSFP GEN2 optical transceiver. The main difference between 40G QSFP GEN2 and existing 40G QSFP on the market lies in the multichannel real-time DDM function, which is easy to realize for transceivers with data rate lower than 10Gbps, but very complicated for those more than 10Gbps, as the latter is mostly based on COB not TO packaging technique. As for parallel high-speed optical transceiver with higher rate, it requires excellent design and precise layout to realize optic circuit detection on 4-channel or 12-channel array light chip in an extremely limited space, which has been met by Gigalight patented optical engine technology. Starting optical engine technology development since 2011, now by its own endeavor and cooperation with quality suppliers, Gigalight has gained rich experience and unique technology about array LENS development and integrated optical devices coupling capsulation. It is a critical mission for Gigalight R&D long-term works that realizing multichannel optical power DDM real-time monitoring of high-speed parallel optical module. Lack of optical power real-time monitoring does not influence optical modules regular operation; however Gigalight‘s been striving to create product higher than industry standard and holds firm pursuit of optical module complete functions, and finally they reach this goal.

“Multichannel parallel optical power real-time monitoring means more to optical network than single-channel transceiver, because any one channel of multichannel module having problem would lead to overall failure. Once it can realize multichannel simultaneous monitoring, it means 40G or 100G module is no longer an uncontrolled black box. With optical power monitoring loopback, engineers can design power automatic feedback compensation circuit, enable the modules adjust to wider temperature range and poor external environment. Multichannel simultaneous monitoring also assures vector compliance of every path. Gigalight 40G QSFP SR4 GEN2 has excellent optic electronic performance, its eye mask margin of each path is 30% higher, and sensitivity all better than -13dbm.” As Gigalight Marketing Department tell so.

It says that Gigalight new launched GEN2 optical module will not largely increase clients’ purchasing cost. The bulk price of GEN1 and GEN2 almost reach equilibrium, even GEN2 module is a truly flawless product compliant with related standards. Gigalight launched this new product at CIOE in September 2015, and now plans to completely switch the generation products in the first half of 2016.

(3) Low-power 40Gb/s QSFP+ SR4 GEN2 optical transceiver: the main advantage of this new module compared to the market popular 40G QSFP module is the multi-channel optical power DDM function, which guaranteed the module specification compliance via real-time monitoring compensation. Its power dissipation is only 1.5W.

(4) Low power & cost 25GE SFP28 SR optical transceiver and AOC: this module has DDM TX POWER real-time monitoring function based on COB craft and Gigalight patented optical engine technology.
